IMPROVEMENT iN GAS=BURNERS.

Specification forming part of Letters Patent No. 124,866, dated March 19, 1872.

Specification describing new and useful Improvements in Gas-Burners, invented by THOMAS WARD, of Columbus, in the county of Franklin and State of Ohio.

This inventionv is chieiiy designed for burners used for burning illuminating-gas made by saturating-air with vapors of gasoline or other light hydrocarbon. It consists iny the novel arrangement of orices or perforations in an argand burner to increase its efficiency; also, in the combination of an internally-screwthreaded and externally-tapered thimble with a 'taper-socket provided at the lower end of the main tube or stem of the iixture, whereby the latter may be securely attached to one of the branches of a gas or kerosene chandelier or to any other suitable support without screwing it on or turning it to adjust it. l

In the accompanying drawing, Figure 1 is a side view of a burner and fixture made according to my invention, and Fig. 2 isa central vertical section of the same.

Similar letters of reference indicate corresponding parts in both figures.

A is the main tube or stem of the fixture. It communicates at the upper end with a reservoir, and near its lower end it has a tube or hollow arm, B, screwed or otherwise secured transversely through it, and its lower end is formed to constitute a taper-socket, a. His a taper-thimble whose lower portion is internally screw-threaded to screw on one of the `nozzles of an ordinary gasolier or other support. When thus secured the upper portion ofthe thimble receives the taper-socket a on the tube A, whereby the latter is secured in place by simply placing it on the thimble without necessitating its bein g turned round. -This enables the burner, with its attached reservoir,

to be applied to a gasolier o`r chandelier onl which there would not be room to turn it to screw it on. In one end of the tube or arm B there is a socket, b, which is separated from the body of the tube by a diaphragm provided with a valve-seat for a valve formed on the end of a thumb-screw, C, screwing through the opposite end of the arm B. Into 'the socket b there is screwed a branch-tube, which is filled with cotton or other similar substance for the purpose of checking or preventing` the too rapid iiow of the gasoline or other liquid to the point of vaporization in the burner. E is a connecting-piece or T, of which the arm al is screwed on the outer end of the branchpipe. The upper, e, of the other arms of this connecting piece is externally screw-threaded, and forms a nozzle for the reception of the burner-socket, and it is provided with a valveseat, within which a taper-valve formed on the end of a thumb-screw, F, works.' The lower arm f has provided at its extreme end a cup to catch any drippings which may escape from the burner, and its interior is taper andl screw-threaded for the reception or'. an externally taper screw-threaded bush, G, of brass or other soft metal, which is also internally screw-threaded to form a nut for the screw F. By screwing up this bush into thescrew-thread in the part f of the T-piece E it will, owing to the taper form of its exterior and its thinness,

be contracted tightly upon the said screw F and take up its wear, and thereby prevent any leakage. around it. The screw F is turned without disturbing this bush G, which is only screwed up when necessary to tighten on the screw F. The burner I, which is of the kind commonly known as argand, has the usual per forated annular tip, and the usual annular chamber communicatingwith two hollow arms,

' It h, formed on a screw-threaded socket, g, by

which the burner is secured on the arm e of the connecting-piece E. The burner is provided, as usual, with a series of holes at its top edge communicating with the annular space before meiitioned5and in addition to these, in the outer side, near its upper edge, is a series,i i, also communicating with the space within the burner. Also, in the upper side of the hollow arms h h there are holes j j, which communicate with the interior. 1n the socket g there is a hole, k, through which air is admitted to the burner. rIhe gasoline or other liquid to be vaporized iows down the main tube or stem A, through the branch-tube and connecting piece E, to the burner, in which it is vaporized. The vapor mingles with air entering the inlet-hole 7c and passes up into the burner, and portions ot' it issue through the holes j j in the arms It h, and those, i t', around the exterior of the burner, where it is ignited in the form of jets, which serve to heat the burner,and so eiiectV more perfect combustion at the tip thereof. The jets issuing through the holes e' also serve to assist in the illumination, though for this I depend mainly on what issues from the usual holes in the tip of the burner. Instead of making the bush G taper, it may be made straight, and the socket f, within which it Works, 'will be tapered, and the same result will thereby be attained.

Claim.

l. The holes i i, neer the top of the exterior of the burner, iu combination with the annular perforated tip, substantially as und. for the purpose set forth.

2. {Ehejet-holes j j in the hollow arms h h of an. irgend burner, substantially as und for the purpose herein described.

3. The combination, with the taper-socket a, connected with the mein tube A, of the internally-soreW-threaded thimble H of taper exterior, substantially as and for the purpose described.
